Optimize poller throttling parameters in indexer_metrics_collector

[francisdouglas-ux]

Problem & Goal

Implement dynamic polling frequency intervals in indexer_metrics_collector based on ledger processing loads.

Context & Components

• Target Repository: escrow-backend
• Module/Component: indexer_metrics_collector (Poller performance telemetry tracker)

Implementation Details

1. Review the existing codebase inside the escrow-backend directory.
2. Locate the source files relating to indexer_metrics_collector.
3. Implement the feature logic/validation rules step-by-step.
4. Ensure code conforms to codebase patterns (lints, formats, types).

Verification & Testing Requirements

• Validation check: Assert polling wait delays increase if network is idle.
• Add comprehensive test cases matching these validation requirements.
• Ensure all other existing project tests continue to compile and pass.
